This application claims the benefit of the French patent application No. 1651067 filed on Feb. 10, 2016, the entire disclosures of which are incorporated herein by way of reference.
The present invention relates to a control device of a communication system of an aircraft, notably a transport airplane. In the context of the present invention, a communication system is understood to be a set of standard communication equipment items, making it possible to implement and control audio communications on board the aircraft. These audio communications are, in particular, all those that the pilots of the aircraft can have, notably with air traffic control (via VHF channels or HF channels for example), with the airlines (via VHF channels or even a channel corresponding to a telephone link, for example over the “SATCOM” network), with the crew in the passenger cabin of the aircraft (via a channel corresponding to a cabin intercom), with the passengers (via a channel corresponding to a public address link, between pilots (via a cockpit intercommunication channel), etc.
To control such a communication system (that is to say all the communication equipment items), the pilots generally use a standard device of ACP (Audio Control Panel) type. This device of ACP type makes it possible to mix several communication channels in reception: radio communication (VHF, HF, etc.), SATCOM telephone link, cabin intercom, etc. This mixing enables pilots to listen simultaneously to several channels, with the possibility of setting the sound volume of each of the channels by means of buttons for setting sound volume of the device of ACP type. The ACP device further allows a user, such as a pilot, to select a communication channel for transmission (one channel at a time).
In addition to the device of ACP type, the pilot usually has a frequency setting device of RMP (Radio Management Panel) type, of RCP (Radio Control Panel) type or of RTP (Radio Tuning Panel) type, for setting the radio frequencies of VHF and HF radio communication channels. He or she can also manually select or set telephone numbers, via the SATCOM system for example, generally from a page that can be displayed on a device of MCDU (Multipurpose Control and Display Unit) type, or even from the frequency setting device.
The document FR2.821.468A1 describes a control device of a communication system incorporating the functionalities of a device of ACP type, of a device of RMP (or RCP or RTP) type, as well as telephone number selection or setting.
The device of ACP type, whether independent or incorporated in a control device such as that described in the document FR2.821.468A1, comprises a set of buttons for each communication channel of the controlled communication system. This set of buttons includes a button for setting sound volume (generally a rotary knob), a listening button making it possible to select or deselect listening to the corresponding communication channel and a transmission button making it possible to select or deselect the corresponding communication channel for transmission. In the case of a conventional communication system comprising, for example, two VHF channels, two HF channels, two channels corresponding to SATCOM telephone links, a cabin intercom channel, a public address channel and a cockpit intercommunication channel, the device of ACP type comprises nine sets of buttons corresponding to the abovementioned nine communication channels. This high number of buttons results in a significant footprint of the sets of buttons on the front panel of the device of ACP type. That also contributes to increasing the weight of the device of ACP type. Furthermore, the cost of the buttons, in particular of the rotary knobs, is high.
An aim of the present invention is notably to provide a solution to these problems. It relates to a control device of a communication system of an aircraft, the communication system having a predefined number of communication channels, the device comprising a processing unit, a display screen and sets of buttons, each set of buttons being associated with a communication channel and comprising:
This device is noteworthy in that:
Thus, the control device of the communication system comprises a number of sets of buttons, less than the number of communication channels likely to be controlled by the control device. That makes it possible to reduce the footprint, the cost and the weight of the control device. Furthermore, since the association between a set of buttons and the communication channel associated with this set of buttons can be configured by the processing unit, if a new communication channel is added to the communication system, the control device can continue to be used, subject to a simple updating of its software in order to take account of this new communication channel. The fact that the number of sets of buttons is at least equal to two makes it possible for a pilot using the control device to be able to easily and quickly control several communication channels with which he or she has to interact at a given instant, without requiring frequent reconfigurations of the channels associated with these sets of buttons.
According to particular embodiments that can be taken into account in isolation or in combination:
the processing unit is configured to display an indication in the display area associated with the set of call buttons when the communication system receives a call over a communication channel with which no set of buttons is associated and to select this communication channel for transmission following an action of a user on the transmission button of the set of call buttons.
The invention also relates to an aircraft comprising a control device of a communication system as mentioned above.
The invention will be better understood on reading the following description and on studying the attached figures.
In an aircraft, such as the aircraft 1 represented in
The sets of buttons 12a . . . 12d are reconfigurable, that is to say they are provided to be each associated with a communication channel of the communication system of the aircraft and a user can configure the association between each set of buttons and the communication channel associated with this set of buttons. Each of the sets of buttons 12a . . . 12d comprises a button for setting sound volume, respectively 14a . . . 14d and a reception button, respectively 15a . . . 15d. The reception button is provided to activate or deactivate listening to the communication channel with which the set of buttons to which it belongs is associated, by successive presses on this reception button. This reception button can be located on an end of the button for setting sound volume, which allows for a greater physical integration of the buttons and therefore a space saving. That also allows for a better ergonomy of use, in as much as the button for setting sound volume and the reception button of one and the same communication channel are located together. A display area, respectively 18a . . . 18d, defined on the display screen 35, is associated with each of the sets of buttons, respectively 12a . . . 12d. The display area associated with a set of buttons is arranged facing at least one button of the set of buttons and it is provided to display at least the name of the communication channel associated with the set of buttons.
In a first embodiment represented in
In operation, when a user such as a pilot of the aircraft performs an action on a button of one of the sets of buttons, the processing unit 40 conventionally accordingly controls the interactions between the microphone, the loudspeaker and the equipment items corresponding to the communication channel associated with this set of buttons. Thus, when the user presses on the reception button, the processing unit activates listening, on the loudspeaker 44, to the communication channel associated with the set of buttons. When the user presses the transmission button, the processing unit selects the communication channel associated with the set of buttons for transmission. If necessary, the processing unit deselects another communication channel previously selected for transmission, given that just one communication channel can be selected at a given instant for transmission. When a communication channel is selected for transmission, the processing unit allows the transmission of the signals from the microphone 42 to the equipment item 47a . . . 47h corresponding to the communication channel selected.
The processing unit 40 is further configured to configure the association between each of the sets of buttons 12a . . . 12d and the communication channel associated with this set of buttons, according to actions of a user on at least one interactive element of the device 10. In a particular embodiment, the interactive element corresponds to the transmission button 16a . . . 16d of the communication channel Advantageously, when a user presses for a long time (for example for longer than 2 seconds) on the transmission button of a set of buttons, the processing unit activates a configuration mode for the communication channel associated with the set of buttons. The processing unit then controls the display, on the display screen 35, of a menu or of a list allowing the user to choose the communication channel that he or she wants to associate with the set of buttons. In another particular embodiment, the device 10 comprises navigation keys 33a, 33b, 33c distinct from the sets of buttons and the interactive element corresponds to one of the keys, for example the key 33a. The processing unit is configured to commence configuration of the communication channel associated with a set of buttons when a user presses on this key. The processing unit is configured such that the user can then, initially, choose the set of buttons for which he or she wants to configure the associated communication channel (for example by means of the other navigation keys) and, secondly, choose the communication channel, for example, in a menu or in a list as described previously.
Once the communication channel is chosen by the user, the processing unit stores, in a memory, the association between the set of buttons concerned and this communication channel. The processing unit further controls the display, in the display area associated with the set of buttons, of the name of the communication channel, for example VHF1, VHF2, HF1, HF2, TEL1, TEL2, NAV or CAB.
According to a particular embodiment of the first embodiment, the control device 10 comprises sets of keys 32a, 32b situated in proximity to the display screen 35. These keys can, for example, be used conventionally to make choices in menus.
In another particular embodiment of the first embodiment, the control device 10 comprises sets of buttons 30, 31. Physically, these sets of buttons are similar to the sets of buttons 12a . . . 12d, but they are not reconfigurable: they are associated with communication channels, in a way that is preset and cannot be modified by a user. The communication channels with which these sets of non-reconfigurable buttons are associated correspond to communication channels over which a pilot of the aircraft needs to be able to interact rapidly at any instant, without requiring a reconfiguration of the association between a set of buttons and one of the channels. They can, for example, be channels corresponding to cockpit intercommunication between two pilots or to addressing the passengers (public address channel).
According to yet another particular embodiment of the first embodiment, the control device 10 comprises a keyboard 28. This keyboard makes it possible, for example, to enter numeric values, in particular for setting radio communication frequencies, for inputting telephone numbers, etc.
In a second embodiment represented in
The processing unit 40 is configured to configure the communication channel associated with each set of buttons according to actions of a user on at least one interactive element of the device 10. In a particular manner, the interactive element corresponds to the transmission button of the communication channel, that is to say to the touch surface superimposed on the display area associated with the set of buttons. Advantageously, when a user performs a specific gesture on this touch surface, the processing unit commences configuration of the communication channel associated with the set of buttons concerned by activating a configuration mode for the communication channel associated with the set of buttons. In a particular embodiment, this specific gesture corresponds to a prolonged press (for example for longer than 2 seconds) on the touch surface. In another particular embodiment, this specific gesture corresponds to the dragging of a finger of the user over the touch surface, as illustrated by the arrow F1 in
According to a particular embodiment of the second embodiment, the control device 10 comprises sets of buttons 31 and (36, 38). These sets of buttons are not reconfigurable: they are associated with communication channels in a preset manner and cannot be modified by a user. The communication channels with which these sets of non-reconfigurable buttons are associated corresponds to communication channels over which a pilot of the aircraft needs to be able to interact rapidly at any instant, without requiring a reconfiguration of the association between a set of buttons and one of the channels. For example, the buttons 36 and 38 are associated with the communication channel corresponding to cockpit intercommunication between two pilots and the set of buttons 31 is associated with the communication channel corresponding to passenger address (public address channel).
According to another particular embodiment of the second embodiment, the control device 10 comprises keys 39a and 39b corresponding to particular functions of the device.
According to yet another particular embodiment, not represented, of the second embodiment, the various buttons of the sets of buttons 12a . . . 12b correspond to touch surfaces of the screen 35. The control device 10 can then have no electromechanical button.
Although illustrated in the particular case of the second embodiment, the rest of the description is not limited thereto and it applies equally to the case of the first embodiment.
Advantageously, the control device 10 is linked to a pointing device and the processing unit is configured to commence configuration of the communication channel associated with the set of buttons concerned when a user interacts with the display area 18a . . . 18d associated with the set of buttons 12a . . . 12d concerned by means of the pointing device. The pointing device corresponds for example to a device of “trackball” type of a human-machine interface of the cockpit of the aircraft, for example a human-machine interface of KCCU (Keyboard and Cursor Control Unit) type. Thus, for example, a user brings up on the display screen 35 a cursor associated with the pointing device. He or she moves this cursor over the display area associated with the set of buttons for which he or she wants to reconfigure the communication channel When the cursor is on the display area, the user can then click by means of the pointing device. Since the latter is linked to the processing unit 40, the processing unit interprets this clicking action as a request from the user to commence configuration of the communication channel associated with the set of buttons concerned and it controls the display, on the display screen 35, of a menu or of a list in which or from which the user can choose a communication channel by means of the pointing device.
Even more advantageously, the processing unit is configured to display, on the display screen 35, a so-called configuration menu, on request from a user, this configuration menu allowing the user to choose from several preset configurations of the channels associated with the various sets of buttons. In the example represented in
In an advantageous embodiment, the control device 10 comprises a set of buttons 20, called set of call buttons. This set of call buttons comprises at least one transmission button. The control device 10 further comprises a display area 26 on the display screen 35, this display area being associated with the set of call buttons and preferentially arranged facing the set of call buttons. The processing unit 40 is configured to display an indication in the display area associated with the set of call buttons when the communication system receives a call over a communication channel with which no set of buttons is associated and to select this communication channel for transmission following an action of a user on the transmission button of the set of call buttons. Upon the action on the transmission button, the processing unit further activates listening on the communication channel According to a variant button embodiment represented in
When a call is received by the communication system over a communication channel with which one of the sets of buttons 12a . . . 12d is already associated, the processing unit controls the display of a “CALL” indication in the display area 18a . . . 18d associated with this set of buttons. In the example illustrated by
In a variant embodiment, the processing unit is configured to display an indication in the display area 26 associated with the set of call buttons 20 when the communication system receives a call over any channel, even if a set of buttons 12a . . . 12d is already associated with this channel. This simplifies the ergonomy of use of the device by the pilot, since the latter can then always answer a call by performing an action on the transmission button 24 of the set of call buttons.
Advantageously, when a user, in particular a pilot, wants to transmit a call over a communication channel with which no communication channel is associated, this communication channel corresponding to a telephone link, the pilot sets the corresponding telephone number in an appropriate menu of the control device 10. This menu corresponds for example to the “TEL” tab of the list of tabs 60 represented in
In a particular embodiment, the processing unit 40 further controls the display of a sound volume indicator 19a . . . 19d, or 27 in the display area associated with each set of buttons, as represented in
In another embodiment, that can be combined with the preceding one, a visual indicator is combined with the reception button 15a . . . 15d of each set of buttons. In the example represented in
Advantageously, when a communication channel is activated for transmission, the processing unit controls the display of a background of a specific color for the display area associated with the set of buttons associated with this communication channel For example, the background of the display area is gray when the display area corresponds to a communication channel not activated for transmission and this background is green when the display area corresponds to a communication channel activated for transmission. Even more advantageously, the processing unit controls the display of a background of another specific color upon the reception of a call over a communication channel, in addition to the display of the “CALL” indication already mentioned.
The functionalities of the transmission, reception and sound volume setting buttons of each of the sets of buttons can be incorporated on one and the same control device without departing from the scope of the invention.
While at least one exemplary embodiment of the present invention(s) is disclosed herein, it should be understood that modifications, substitutions and alternatives may be apparent to one of ordinary skill in the art and can be made without departing from the scope of this disclosure. This disclosure is intended to cover any adaptations or variations of the exemplary embodiment(s).
